It would be a better way to provide electricity by collecting energy for wirelesspurposes. "Energy harvesting" is a technology that converts the excess energy available in theenvironment into energy that can be used for low-power electronics. A lot of ambient energysources have been considered for this purpose as the incident light, vibration, electromagnetism,radio frequency (RF), the function of the human body, the temperature gradient and others.Based on the literature, different energy sources and techniques of collecting energy to powerMEMS sensors used TE-Core.IntroductionEnergy harvesting (also known as power harvesting or energy scavenging), or ―Micro-Generators‖ in the literature, is a process performed by a conversion mechanism for generatingelectric power from available ambient energy sources. Incident light, thermal gradients, machinevibrations and human body functions are the well known examples of ambient energy sourcesreceiving the attention of many researchers. Since energy harvesting systems offer maintenance-free, long-lasting, green power supply for many portable, low-powered electronic devices, theyare likely to become an essential part of power management systems.Figure 1. Wireless Self-powered Sensor NodesThe growing interest in the field of energy harvesting systems is also due to greatdevelopments in related technologies such as micro-electromechanical-system (MEMS)technology, wireless sensor network (WSN) technology, very large scale integration (VLSI)design technology, and complementary metal oxide semiconductor (CMOS) fabrication

Sensors emerge as a promising application of energy harvesting techniques wherethese state of the art technologies work together as shown in figure 1.Energy harvesting from ambient energy sources for MEMS sensors and low-power electronicdevices is an active research topic with growing application areas such as wireless sensornetworks and wearable devices. As the power consumptions of the electronic devices aredecreased by the advancements in micro fabrication techniques, various energy sources includingincident light, thermal gradient, human body functions and vibrating industrial machinery whichare available in the environment have aroused the interest of many researchers as ambient energysources convertible into electric energy. However, ambient vibrations stand out as a promisingand convenient energy source for many applications among others, since they are usuallyavailable continuously and abundantly in the surroundings of the energy harvesting systems.Energy Harvesting for Wireless Sensor NetworkThe concept of energy harvesting in relation to wireless sensor network (WSN) entails theidea of scavenging energy from mechanical, vibrational, rotational, solar or thermal means ratherthan relying on mains power or alkaline/rechargeable batteries to power the sensor nodes in theWSN. For instance, power can be harvested from the mechanical force of a conventionalmechanical ON and OFF switch being turned on or off. Alternately, power can be derived fromthe difference in temperature between the human body and the surrounding ambientenvironment. Energy harvesting is increasingly gaining notice in the WSN research as well asindustry market because it is a very potential solution to extend the lifetime of the sensor node‘soperation.“The industrial market will be the second key area for energy harvesters, again withapplications in wireless sensors that are used to monitor machines and processes”, announcesAntoine Bonnabel, Technology & Market Analyst, MEMS Devices & Technologies at YoleDéveloppement. Energy harvesters increase the autonomy of the battery and thus themeasurement data rates which are today limited with batteries. Maintenance free is also a greatargument for EH in those applications where accessibility is sometimes critical (oil & gasindustry for instance). ―Today, sales are limited because there is no real agreement on a lowpower radio protocol, as in buildings, but this will soon change and will allow significant pricereduction and production ramp-up to several hundred thousand units in 2017‖, pursues AntoineBonnabel.Figure 2.

Mechanical EngineeringMicro Electro Mechanical Systems (MEMS)Degree Bridging Indonesian Student 2013 40To ensure continuity in the load operation even when the external power source is temporarilyunavailable, the excess energy harnessed has to be stored either in a rechargeable battery orelectrochemical double layer capacitors, also known as supercapacitors/ultracapacitors. Thepower conditioning electronic circuits in the energy harvesting system are designed based on theenergy harvesting input energy sources and the connected output loads, hence different types ofpower conditioning circuit designs have been proposed to bridge between the source and theload. It is worth noting that the design of the energy harvesting system to power the sensor nodein the WSN may differ from one application to another application because of the variations inthe load requirements and the differences in the condition of the deployment area.TE-COREThe TE-CORE is a complete thermo-powered, self sufficient wireless sensor node system(WSN). The TE-CORE thermoharvesting module converts locally available waste heatthermoelectrically to indefinite free electric energy-as long as the heat flows through thethermogenerator (TEG). The integral power conversion and management circuit steps up the‗gradient–analog‘ output voltage of the TEG at a fixed voltage (2.4 V by default). The harvestedenergy is being buffered in an extendable capacitor and controlled by a configurable hysteresis.Figure 3. based on an Energy Harvesting module.Design TE-COREThe Energy Harvesting module of the TE-CORE /RF operates from a heat (or cold) thermalenergy source. The TGP‘s aluminum top side, its thermal input, is supposed to be attached to theheat source. The thickness of the thermal input acts as a spacer to protect the PCB and to ensurea thermal separation between the hot and cold sides; i.e. optimizing energy harvestingperformance through suppression of thermal ‗cross talk‘The TE-CORE /RF is based on an Energy Harvesting module with powermanagement function, which converts locally available waste heatthermoelectrically to indefinite free electric energy.A Wireless Sensor module is connected to the TECORE /RF and isequipped with Texas Instruments (TI) ultra-low power technology (CC2530).
